If the pH of a chemical system is 8.91, then what is the hydrogen ion activity of the system in mol H30*/L? Please answer to at least three significant figures: This means three digits after any leading zeroes, so a good answer would have a form such as 0.0000XYZ or 0.0XYZ mol H30*/L, where XYZ are the significant figures.
